Is this a good build?

Don't need the rockers either. Somebody wants to sell lots of parts to you! 54's have a smaller base circle, .020 in your favor. I am running stock pushrods with mine.
Could be a good build...but that all depends on if it matches your riding style! It's only good if it does what YOU want it to!

1) You dont need adjustable pushrods, at all.
2) You need to have Big Boyz install compression releases. Bigger valves would be nice.
3) The stock beehive valve springs are perfectly fine.
4) SE tuner.....why? Seeing as you are so remote to a good tuner, get the TTS system.
5) If you want real power, you are going to need a 2-1 exhaust system.
6) Don't forget you need cam sprocket spacers from HD.
7) Drill your rocker box oil drain holes out larger to prevent oil misting. There is a link to the Doherty website somewhere that explains this.
8) Why do you need tappets? If you REALLY want to install new tappets, then just buy some Crane 10530-2 (2 sets = 4 lifters) from a SB Chevrolet, as that is the same lifter SE uses.
Honestly, if you are doing CP forged pistons (and not just using SE 103" kit), then why not go 107" pistons?
Seeing as how JCK just went through all of this, he would be a good one to chime in.

You don't need the springs for those cams. They will only make it noisier.

The 54's have a wide torque band. Will suit many riding styles.

Thanx guys, but im getting confused now!! The mechanic in my HD dealer is saying I do need new tappets & pushrods. My riding style is aggressive, I hit the rev limiter at least twice every time i ride thats why I thought I need new valve springs.

I've got SE Flat tops on my build, stock rockers, stock pushrods and stock valve springs. All are working just fine.
Lifter replacement is not a bad idea if yours have more than 10k miles on them, but no need for anything other than stock if you are replacing them.

No need for the rockers, just get a cam with the lift you want to match your build.

I didn't realize from your earlier posts that they had the ratio.
Most people say that you should gain your lift from choosing the appropriate cam. It makes good sense what they say.
However, I have seen cases before where people were pleasantly surprised by adding lift via rocker ratio. I have not seen this tried with the 54's yet. You can be our Guinea pig.
This cam has a very wide torque band. I'd love to see what adding some lift would do! Also, this may be why they are recommending springs in your heads. The stock springs are fine with the lift of the 54's, but adding that rocker ratio may change that.
Please, promise to show us a dyno sheet when done! PM me if you have to. Good results on your build might have me rethinking mine! This might just end up being a very good thing.

A few years ago on another forum there was a dyno posted that everyone thought was fake. He was just too far above the others with the similar build and cam.
The tuner was credible and his dyno was known (not for being generous).
A few pages into the thread it was mentioned about his rocker ratio.
Sure it made the dyno sheet comparison unfair,..... (but he gained power).
'nuff said?
